As technology advances at a rapid pace, we often find ourselves nostalgic for simpler times. The days of sleek slide phones hold a special place in many people's hearts, and for those who yearn to relive that era, creating a DIY slider phone can be a rewarding project.

In this comprehensive guide, we will embark on a step-by-step journey to build your very own retro slider phone. From gathering the necessary materials to refining the final product, we will cover every aspect of the process to ensure you achieve a functional and stylish device.

Materials
Raspberry Pi Zero W or Zero WH
GSM/GPRS HAT for Raspberry Pi
4G/LTE HAT for Raspberry Pi (optional)
2x 18650 batteries
Battery holder for 18650 batteries
DC-DC converter (5V to 3.3V)
LCD screen (3.5 inches or smaller)
Keyboard membrane (optional)
3D-printed case
Slider mechanism (linear bearings and rods)
Various screws, nuts, and bolts

Step 1: Assembly

Begin by assembling the Raspberry Pi, GSM/GPRS HAT (and optional 4G/LTE HAT), and batteries. Connect the DC-DC converter to the Raspberry Pi and batteries to power the device.

Step 2: Software Installation

Install the necessary software on the Raspberry Pi, including Raspbian OS, Python, and the GSM/GPRS libraries. Configure the GSM/GPRS module for your network provider.

Step 3: LCD and Keyboard Setup

Connect the LCD screen to the Raspberry Pi and configure it using the appropriate drivers. If desired, attach a keyboard membrane for user input.

Step 4: Create a Slider Mechanism

Design and print a 3D-printed case that accommodates the slider mechanism. Install linear bearings and rods to enable smooth sliding.

Step 5: Integrate the Components

Mount the Raspberry Pi, LCD screen, and keyboard (if applicable) inside the case. Connect the slider mechanism to the sliding portion of the case.

Step 6: Case Design and Decoration

Finalize the 3D-printed case design and decorate it with your preferred aesthetics. Consider adding custom patterns, logos, or colors to create a unique look.

Step 7: Testing and Troubleshooting

Thoroughly test the slider phone's functionality, ensuring that the sliding mechanism operates smoothly, the LCD screen displays properly, and the GSM/GPRS module establishes a connection.
